In a short video feature, BBC’s Spencer Kelly recently featured a Tokyo sushi restaurant that is practically automated and gives a glimpse at how technology has been changing the conveyor belt concept. Kelly, who was in Tokyo for the CEATEC technology fair, takes viewers on a quick tour of the restaurant.

There are no waiters to take down orders. Instead, diners use a touchscreen to make special requests, which are delivered via the conveyor belt. When finished with a dish, diners simply have to put the empty dish into a slot that takes the dishes back to the kitchen and also serves as a tally of the dishes consumed. Every time a diner drops five plates down the slot, it triggers a game on the screen and the diner can win small tokens that pop out automatically.

Not everything is automated of course. The kitchen has people preparing the dishes and diners have to face a cashier when they pay.

Kelly doesn’t mention the name of the place, but it isn’t surprising for the journalist to stumble into such a restaurant. Kaitenzushi or conveyor belt sushi is certainly not new in Japan and automated serving systems are becoming commonplace in many sushi restaurants in the country and in parts of the world.
